Add support for non english numbers in BitNumberField component

Is there an existing issue for this?

Is your feature request related to a problem? Please describe the problem.

The BitNumberField won't accept Persian numbers as valid digits.

More context on the problem:

There are several Language Packs available for Persian.
Let's say I have not passed in any format to the Format parameter. Hence, the underlying input element has a type=numeric attribute (based on your current implemnetation).
Now whether the input works as expected depends on the current language selected (Look at the image below too):

• English (last item in picture) <-- works
• Persian (First item in picture) <-- works
• Persian (Iranian Standard Persian keyboard) <-- doesn't work
• Persian (Persian (Standard) Keyboard) <-- doesn't work
  

The problem occurs only if I use the top row keys of keyboard for entering numbers (not the numeric pad on the right-side of physical keyboards)

Describe the solution you'd like

I have the idea of mapping the literal strings like ("۱", "۲", "۳", ...) to their equivalent English characters.
I can see that this idea is not aligned with the fact that your implementation so far is not bound to any specific culture and this solution won't scale to a generic solution suitable for all cultures.
Given all the nice multi-lingual capabilities, I hope finding some more robust solution.

Additional context

Though suggested by numerous resources that setting lang attribute will help the problem, I tested and can verify that it won't help the described problem.
